As the title suggests, I would like to know what specific method is called to display the results of the evaluated cell in Pluto.

The problem that I am trying to solve is why `Latexify.jl` works for real symbolic matrices from `Symbolics.jl`, but not for complex symbolic ones.

I have to figure out the dispatch tree, and for that I need to know which specific method of `display`, `show` or whatever function Pluto uses by default.

It uses `show` with the MIME type `text/latex`. The list of used MIME types used by Pluto.jl is here: [Pluto.jl/PlutoRunner.jl at c9ac544dbbd3fdbc3aabaf89ea911101f42a1026 · fonsp/Pluto.jl · GitHub](https://github.com/fonsp/Pluto.jl/blob/c9ac544dbbd3fdbc3aabaf89ea911101f42a1026/src/runner/PlutoRunner.jl#L992)

Symbolics implements that here

To extend it, you need to implement something like

```julia
Base.show(io::IO, ::MIME"text/latex", x::YourType) = print(io, "\$\$ " * latexify(x) * " \$\$")

```

where `YourType` is the type you want to support.
